Creo Parametric CAD Modeling Challenge
For this third Creo Parametric CAD modeling challenge, you will be creating a full assembly of the 4 bar linkage shown below. You need to know basic Creo Parametric assembly constraints, Kinematic constraints and assembly structure to complete the design. It is a fairly simple model to create, but you will need to master Creo Parametric Pin constraints to make it work correctly.
HINTS
- Create sub-assemblies for the fixed and moving components with equally spaced linkage arm mounts
- Assemble the fixed sub-assembly first and make sure it is grounded
- Add all the hardware at the end
- Set limits for the first control arm to make sure the mechanism does not freely rotate through 360 degrees
- Use a second set of constraints to connect the moving sub-assembly to the linkage arms
- Watch a video of the motion
Extra Credit
- Create a copy of the linkage arm and try different lengths
